ESPN's Adam Schefter reports Rob Gronkowski's potential back operation is considered "minor," and wouldn't necessarily sideline him any longer than his arm surgeries.
The back surgery is considered "likely," per NFL Net's Albert Breer, but Schefter reports the operation would take place within the timeframe of Gronk's absence due to a fourth arm procedure. "He is going to be fine long term," said a source close to Gronkowski. "(He is) not worried about the short term, i.e. start of training camp." Either way, multiple offseason surgeries on multiple body parts are cause for major fantasy football alarm. And the fact that Gronkowski is in line to have had two back surgeries since 2009 is absolutely a long-term worry.
